Oral devices for reducing obstructive sleep apnea, snoring and/or nasal drainage, or improving sleep even without substantial reduction in snoring. One device includes an upper member fitting portions of the interior and exterior surfaces of a user's upper dentition, and a lower member fitting similarly adjacent a user's lower dentition. The upper and lower members include molar and pre-molar extensions so that when a user bites or clenches, the upper right and lower right extensions impinge on one another in substantially overlapping fashion, as do the upper left and lower left extensions. In certain embodiments, patterned surfaces on mating right and left molar and pre-molar extensions reduce friction. The lower and upper molar and pre-molar extensions may have curved or arcuate shaped interior surfaces to provide more room for a user's tongue. Right and left sub-chambers formed in the upper and lower molar and pre-molar extensions may provide lateral space for the tongue. The oral devices may be produced by additive or subtractive manufacturing methods.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.

5. The oral device of claim 1 wherein first and second moldable or printable biocompatible polymeric materials are each selected from a durable fade-resistant acrylic that retains its shape and color for at least four years, and a very pliable, soft, custom-injected silicone.
6. An oral device comprising: an upper generally arched-shaped member that is configured to fit adjacent at least a portion of interior and exterior surfaces of a user's upper dentition, the upper generally arched-shaped member comprising a first moldable or printable biocompatible polymeric material; a lower generally arched-shaped member that is configured to fit adjacent at least a portion of interior and exterior surfaces of a user's lower dentition, the lower generally arch-shaped member comprising a second moldable or printable biocompatible polymeric material, the first and the second moldable or printable biocompatible polymeric materials are same or different; the lower generally arch-shaped member comprising a lower right molar and pre-molar extension and a lower left molar and pre-molar extension, each comprising a moldable or printable biocompatible polymeric material, the lower right and the lower left molar and pre-molar extensions formed integrally with and projecting generally perpendicularly away from the lower generally arch-shaped member and generally toward the upper generally arch-shaped member; the upper generally arch-shaped member comprising an upper right molar and pre-molar extension and an upper left molar and pre-molar extension, each comprising a moldable or printable biocompatible polymeric material, the upper right and upper left molar and pre-molar extensions formed integrally with and projecting generally perpendicularly away from the upper generally arch-shaped member and generally toward the lower generally arch-shaped member; so that when a user bites or clenches, the upper right molar and pre-molar extension impinges on the lower right molar and pre-molar extension, and the upper left molar and pre-molar extension impinges on the lower left molar and pre-molar extension; the upper and lower generally arch-shaped members having an anterior shape to form a gap sufficient for at least a portion of a user's tongue to extend forward into the gap without being impeded in forward movement by the device; the lower right molar and pre-molar extension, lower left molar and pre-molar extension, upper right molar and pre-molar extension, and upper left molar and pre-molar extension configured such that, when the device is in a user's mouth, the molar extensions create a tendency to keep a user's airway open by maintaining the gap; and the lower and the upper generally arch-shaped members are both lacking frontal vestibular upper and lower bands, but upper left and upper right portions are linked together by an upper frontal palatal band, and lower left and lower right portions are linked together by a lower frontal palatal band.
7. The oral device of claim 6 wherein the first and second moldable or printable biocompatible polymeric materials are independently selected from the group consisting of polyurethanes, polysulfones, polycarboxylates, perfluorinated polymers, polyacrylics, polyvinyls, polyvinyl alcohols, silicones, polyolefins, and blends and copolymers thereof.
